This text describes the design and theory of continuous-time sigma-delta modulators for analogue-to-digital conversion in radio receivers. The book's main focus is on dynamic range, linearity and power efficiency aspects of sigma-delta modulators, which are very important requirements for use in battery operated receivers.

This proven textbook guides readers to a thorough understanding of the theory and design of operational amplifiers (OpAmps). The core of the book presents systematically the design of operational amplifiers,

Composed for the 1744 celebrations at Drottningholm Palace of the marriage between the Swedish crown prince Adolf Fredrik and Lovisa Ulrika of Prussia, Johan Helmich Roman's Drottningholm Music is a key work in Swedish art music. Consisting of 24 individual movements, it forms an inventory of short pieces suitable for providing the proper musical ambience for the royal celebrations, which took place over four days. As befitted the occasion, the character of the music is buoyant and witty, and when the atmosphere occasionally veers away from the carefree, it is towards a graceful melancholy rather than grief or pain. This also conforms to the spirit of the time, as does the style of the music itself: varied and brimming with ideas, but never weighed down by dry learnedness or disproportionate displays of emotion. Roman had spent formative years in London in the 1710s, and in the 1730s made a long journey throughout Europe, absorbing the new, ‘galant' currents in music. Although by 1744 he was suffering from failing health, he was at his peak as a composer, and in this sparkling and joyful music he demonstrates both his innate talent and the impressions gathered from music by composers such as Sammartini and Leonardo Leo.

Johan Joachim Agrell (1701-1765) was in many ways a traveller between the worlds: in Uppsala, the Swede's great talent was recognized by the Hessian envoy, which resulted in Agrell being summoned to a court near Kassel in Germany. He later went as municipal chapel-master to Nuremberg. Musically, Agrell was a brilliant Baroque composer in whose works many of the new early Classical trends were anticipated.

This album was created in Lemland/Åland 2015-2017. It's about space and has a connection to my previous space albums and connects everything to an entirety - Space is a source of inspiration, a mystery that will give humanity a continuousunderstanding.Influenced by the early synth masters, such as Jean-Michel Jarre, Vangelis and Tangerine Dream, as well as the progressive rock of Pink Floyd, Tronestam draws sounds from his synths that sweep like plasma fields projecting from the Sun or shift like the light of fading suns. The effect is neither entirely naturalistic nor abstract, but instils the feeling of moving through four dimensions in proximity to almost nothing else.
